Abstract As a kind of dynamic self-organized network, wireless Ad hoc network is faced with serious security threat. On the basis of analyzing the characteristics of Ad hoc network, a hierarchical group key management solution (Hierarchical Group Controller-Based Group Key Management protocol) based on extended Diffie-Hellman protocol is presented. The HGKM utilizes member filter function and hierarchy to maintain a single group key to adapt to the special requirements for frequent key refresh of Ad hoc network.

Key words： Ad hoc network Security;Diffie-Hellman protocol;Group key management
